Tragic all the way around.

Hold an event free of charge, make food available. advertise online, try to get local fishshops/petshops involved(free advertising for minor retail give-aways like fishfood etc.), people/organizations outside the university setting.

From what I could see it looked like the smaller Paroon got that 3rd piece.

No problem Viktor. Really appreciate you posting this amazing build and your journey through it.

I agree with dw1305, I would darken the tank overall, create some darker open areas with plants or plastic plants if you not good with real plants. I would maybe get a school of relatively calm dither fish. My 2¢

Great info on the Thiaminase Viktor. Thanks much.

Regarding your latest post: maybe you can cut it into smaller pieces and see what happens, or try some large earthworms to just get them some much needed minerals?

So sorry to see you lost the big Piraiba, my condolences. But what a gain in knowledge. I've never liked feeding salt water organisms to freshwater organisms as they would, for the most part, never encounter that biology in their natural environment. But I've never had scientific proof to support th...

I'm no expert but closest thing I can see is Hypancistrus L066. Got any more, different angled pics?

Yup, Ameiva sp. Not a native of the US.

Thanks for the info Shane, and that was a great story. Really painted the picture of a smaller dry-season creek (or "cano"?). I have most of those things you mentioned already in place but this tank is an attempt at breeding a rare tetra (Hyphessobrycon jackrobertsi). The group is wild-cau...

Thanks Jools, the L. brinidellii is excellent, but a bit too big for the 40g they would be going into. The C. elegans is a good suggestion, are there any other forest cories I could be looking at?

Thanks for the info Eric, another possibility will be Banjo cats.

Does anyone know of any of the smaller loricariids that prefer living in leaf litter?

Looks like a hybrid from here.

Wow, what a score! jealous.

Great info. Thanks for sharing.

Very sad to see. Hang in there Viktor.

Viktor, what if you pull her out and isolated her in a fry holder or something in the same tank? That way the males can beat up on the container instead of her until her hormones drop off. These are artificial systems we set up; in the wild she may not encounter quite this amount of harassment? I me...

What other fish do you have in the tank? Also, shining a red light and watching after lights out can reveal a lot. my 2¢

Given everything is 'normal' in your tank and with the fish, you should not have any problem putting your Platydoras on a diet. Many catfish her size can go 4-5 days without food no problem.

Nice, whats that made out of?

Thank you all. First I will try the centrifuge technique, then the freezer. I have heard of the freezer trick Eric but this will be the first time I try it myself.

Anyone have a solution to this problem?

You mentioned an Undergravel filter. That may be causing your nitrate problem. I would lift that thing and vac under it. Those filters can harbor poop a 'mile high'... well maybe not that high. But you could have a bunch of uneaten food or even a dead fish under there. Worth the investigation. Other...

Pictus are great 'day active' catfish. A fish I will own at some point. I like my tanks more 'natural' so I would ditch the square stuff and create some overhangs with some larger pieces of driftwood. And try to grow some anubis or Javamoss on the wood which could create some overhangs also. I would...

Thanks for the info Eric. I stumbled on this guy in the fish shop, hiding in about 100 Kuhli loaches. Love good surprises.

Hello, I know these are not great pics but I'm believing this is Microsynodontis polli. Can anyone confirm? If anyone thinks different please speak on why. And if this is S. polli, are there folks here that can speak on any added experience around maintenance, water quality, etc., thats not in the C...

First time ever seeing a lungfish eat. very interesting, masticates like a mammal. Thanks Viktor

The white patch on the head combined with what looks like white dots going down the lateral line in one of the photos and you mentioning that the older cat also has spots (I'm assuming white and on the head) could indicate the beginnings of what is known as Hexamitiasis, "hole-in-the-head"...

From the photos, looks like a male.
